As the temperatures continue to rise and become consistent, HWA will enter its summer dormant stage; however, depending on your location, they may still be a few weeks away.
In some areas, the Hemlock Woolly Adelgid has entered its dormant stage where it stops feeding and settles on the base of Hemlock needles. They will remain in this stage until mid-October when they will begin to infest and feed on your Hemlocks again. In other areas, HWA is still actively feeding and will continue to for a few weeks. Keeping up on your summer rate horticultural oil treatments is imperitive to prevent infestation. Our plant health treatment programs feature multiple visits that ensure HWA is curbed.
Here at Carpenter Costin, we pride ourselves on providing local service across the entirety of the North Shore, Greater Boston, and Merrimack Valley regions. With this range comes variability in pest cycles; therefore, our Arborists are constantly monitoring stages of pest and plant development throughout the North East.
If you are unsure of whether you may have HWA in your Hemlocks, we highly recommend consulting with an Arborist.
